passes through the legs where they cross also 

 passes til rough a slot cut iu this piece of 

 hard wood. Through the lower end of this 

 piece of hard wood is a hole iu which ruus 

 theirou tziulgeou ou the eud of the main 

 shaft. Of course, each pair of legs is fur- 

 nished with such a piece of wood. Each 

 pair of legs is L' ft. T'.j inches apart at their 

 upper ends. The length of the frame, — 

 that is the distance from one pair of legs to 

 the oilier pair is about r> ft. The tops of 

 one pair of legs is fastened to the tops of 

 the other pair by pieces of ."ix:? oak scaut- 

 liuli, bolted on. These pieces of 8x8 scant- 

 ling are about .") ft long, li ft. T^o inches 

 apart, and parallel with each other. Upon 

 the top of these parallel pieces, and at right 

 angles with them, are bolted two pieces of 

 3x3 scantling, 8 ft. l^.j inches iu length. 

 These last-mentioned pieces arealso parallel 

 with each other. The one at the left, as one 

 stands in front of the frame, is lo^.j inches 

 from the end of the framework, aud the 

 other piece (the right-hand one) is 2 ft. 3 

 inches from the front end of the framework. 

 Thej are 14 inches apart. It is upon the 

 top of these pieces, midway between their 

 ends, that are bolted the boxes, or set-screws, 

 of the saw-mandrel. The saw-mandrel is 

 of steel, one inch iu diameter, and about 13 

 inches in length. It is pointed at the ends, 

 and runs iu set-screws. It has a 8x3-inch 

 iron pulley. The saws are S inch. Oh, yesi 

 the mandrel was bought second-hand, at a 

 machine-shop. The larire band-wheel is 4G 

 inches in diameter, and 8 inches across the 

 face. It is made of felloes 8 inches wide, 

 sawed from a pine board. The spokes are 

 made are made of two pieces of pine board, 

 8 in. wide and 44 inches long. They cross 

 each other at the center, and their outer 

 end-* enter mortises cut iu the inside of the 

 rim of the wheel. .\t the center, where they 

 cross, is a 8x3 inch square, mortise for the 

 main slipft, which is a 8x;')-inch scantling 4 

 ft. long, to pass throutrh. The wheel is held 

 in place upon the shaft by a key which holds 

 the spokes firmly against some pieces of 

 planks that are spiked upon the sides of the 

 sh^ft. Around each eud of the shaft is an 

 iron band, and in estch end is driven a gud- 

 geon of ^4 round iron, and upon the end of 

 each gudtreon is a 2 inch crank. That part 

 of the treadle upon which the foot is placed 

 is .") ft. 2 in. long, and comes up behind the 

 operator. To each end of this is fastened a 

 bar of wood 4 in. wide, 1 inch thick, and 

 ofeet 3 inche'^ long. These last-mentioned 

 bars extend to the back park part of the 

 frame, and are fastened to the lower ends 

 of the ' hind ' legs of the machine, where 

 they turn upon the bolts with which they 

 are fastened. These bars pass directly un- 

 der the cranks upon the ends of the shaft, 

 and are connected with them by pitman. 

 To the top of the framework, and at the 

 back side, is fastened the saw-table proper. 

 Through one of the 8x3 pieces that supjiort 

 the saw-mandrel, extends a screw with 

 a crank upon it< lower end This ^^crew 

 is to raise or lower the table. From the floor 

 to the top of the saw-table it is 4 feet ij in. 

 A^ this is too high to work with ease, there 

 is a bench 13 inches high to stand upon. 



The treadle, when it is the lowest, is on a 

 level with this bench. "

In the next number of Gleanings appear- 

 ed the cut that is shown here and accompa- 

 niyng it was the following : 



"The framework that projects at one end 

 of the saw-table is to support one end of a 

 long board, while cutting pieces from the 

 opposite end. The piece A can be raised 

 or lowered so as to have it on a level with 

 the saw-table. It is hinged at the back end, 

 and is held in position by a thumb-screw 

 that passes through a slot in the standard B. 

 When not in use, this framework can be 

 shoved, telescopic fashion, into the machine. 

 C is a gauge that works parallel to the saw. 

 There is a piece of wood fastened to the 

 back end with screws, that p-oje2l8 an inch 

 below the edge of the saw-table, and at the 

 front end is a thum -screw (D) that turns 

 against the front edge of the table. A piece 

 of hoop iron is nailed against the front edge 

 of the table for the thumb-screw to work 

 against. The saw can be seen peeping 

 through the table at E, The screw that 

 raises the saw-table can be seen at F. G is 

 the little bench upon which the operator 

 stands, while the treadle-bar H comes up 

 beh\nd him. The top of the treadle-bar 

 never goes lower than the top of the bench 

 G. In order to make the pitman as long as 

 possible, a piece of wood (I) is bolted to 

 each side treadle- bar, and to the lower ends 

 of these pieces of wood are fastened the 

 lower ends of the pitmans. .J and K are 

 braces. L and M are the pieces upon which 

 the boxes of the saw mandrel rest. 



In order to make the large wheel heavy, 4 

 large stones are fastened inside, one at the 

 edge of each spoke. These stones cause so 

 many ' shadows ' that they were taken out 

 when the picture was taken. " 



In the next number of Gleanings after 

 the one containing the foregoing there 

 appeared the following : 



"The illustration of my buzz saw, in the 

 la«t Glf^anings, is excellent, and with the 

 exception of the hearings of the main shaft, 

 shows every part quite distinctly. Had I 

 known how to properly use the sketching 

 camera, I do not think there would have
